Obscuration Remote and Local Functional Test Capability Wide Range of Input Voltage 10.2 to 36.8 Vdc Low Current Design Dual Response LEDs Allow 360-degree Viewing Trouble Indication Low Profile Appearance Using Surface Mount Technology Electrically and Mechanically Compatible with all Fenwal Smoke and Electronic Heat Detectors and Bases Interchangeable 2-Wire and 4-Wire Bases Universal Relay Modules Non Polarized Locking Feature for Vandal Resistance Fine Mesh Insect Screen EMI and RFI Resistant DESCRIPTION The Fenwal Models PSD-7157 and PSD-7157D Photoelectric Smoke Detectors respond to a broad spectrum of both flaming and smoldering fire conditions. The Detectors have advanced solid-state, low-voltage, surfacemount circuitry and are designed for 2-Wire and 4-Wire installation using the appropriate Detector base. The characteristic 360-degree detector design permits smoke entry from any direction. A unique sensing chamber design permits the operation of the Models PSD-7157 and PSD-7157D in open areas with air velocities from 0 to 300 fpm and 0 to 4000 fpm respectively. The Model PSD-7157D is also suitable for duct housing applications in air velocities from 500 to 4000 fpm. The Detectors are designed for open area/duct housing applications per UL268/UL268A and may be installed in systems intended for Releasing Device Service through use of compatible Fire Alarm Control Panels. TM Effective: May 2007 Protection Systems A UTC Fire & Security Company Two Red Light Emitting Diodes are located diametrically opposite each other so as to allow 360-degree viewing. Both LEDs continuously indicate the operating condition of the Detector. During standby, the LEDs flash once every six seconds. During alarm, both LEDs light steady at full brilliance. A double flash every six seconds indicates a detector with a sensitivity threshold outside acceptable limits. A unique gated output circuit design provides improved stability and transient suppression. Special signal processing techniques verify the presence of smoke before the detector will alarm. A fine mesh insect screen protects the chamber area and is used to avoid potential nuisance alarms. The detector head is installed into the base with a simple twist-lock action. A locking feature is provided for vandal resistant security. CONTROL UNITS The Models PSD-7157 and PSD-7157D Detectors are designed for operation with control units and releasing devices having specific voltage and current characteristics that are compatible with the detector circuitry. The Detectors are compatible with the Fenwal control units and interface modules listed in Table 1. DETECTOR BASE OPTIONS The Models PSD-7157 and PSD-7157D can be used with the detector base options and accessories in Tables 3 and 4. Various base options are available to provide auxiliary relay and/or remote indication and remote test feature. R

The Models PSD-7157 and PSD-7157D Photoelectric Smoke Detectors may be interchanged with other Fenwal Series THD-705X Electronic Heat Detectors and Series CPD-705X Ionization Smoke Detectors when using multifunction base configuration. SPACING (OPEN AREA LOCATION) The Models PSD-7157 and PSD-7157D Detectors are listed to be installed on maximum 30 foot (9.1 m) centers, typically on smooth ceilings up to 15 feet (4.6 m) high and will operate with minimum air circulation. Resultant maximum 900 square foot (83.6 m 2 ) spacing may be used as a reasonable guide for comparable applications. Where special conditions exist (ceiling obstructions, high air exchange rates, etc.), reduced spacing must be used to achieve adequate protection. Computer rooms and other such installations may require spacing with a maximum of 200 square feet (18.6 m 2 ) due to high air exchange rates. Detectors should not be located in areas with excessive exhaust fumes, kitchen areas, near fireplaces or furnace rooms and within three (3) feet (.9 m) of air supply ducts or air diffusers. For additional information, consult the Fenwal Automatic Fire Detection Application Engineering Manual MC-402, NFPA-72 and the local Authority Having Jurisdiction. WIRING DIAGRAMS For detailed wiring diagrams with Fenwal 2- and 4-wire bases, please refer Fenwal Document 70.104 INSTALLATION Detector bases are directly mounted on the electrical junction boxes (3-inch, 3-1/2-inch and 4-inch octagonal, 3-inch round or 4-inch square) (76 mm, 89 mm, 102 mm octagonal, 76 mm round or 102 mm square) without the need for any mechanical adapter required. Refer Fenwal Document 06-235056-001 for additional details. The detector bases also include a locking feature that prevents removal of the detector without use of a tool. TESTING AND MAINTENANCE Testing shall be performed upon installation of the detector and once a year thereafter as stated in NFPA-72 latest edition. Detector sensitivity shall be checked within one year of installation and every alternative year thereafter as stated in NFPA 72. Refer Fenwal Documents 06-236524-001 and 06-235056-001 for details on using the Infrared Wireless Sensitivity Tester Model DST-003. The tester provides direct readout in percent per foot obscuration from a distance of 15-feet without removing the detector from its base. A go/no-go test can be performed using a test magnet. The recommended requirement for detector maintenance consists of an annual cleaning of dust from the detector head by using the suction of a vacuum cleaner. Cleaning programs should be geared to the individual environment in conformance with NFPA 72. CAUTION Do not attempt disassembly of the factory sealed smoke detector. This assembly is sealed for your protection and should not be opened for servicing. Opening of the detector will void its warranty. SPARE PARTS The Models PSD-7157 and PSD-7157D Detectors are factory repairable only and have no field serviceable spare parts. No field repair should therefore be attempted. For service, return detector head intact to Fenwal. ARCHITECT/ENGINEER SPECIFICATIONS The contractor shall furnish and install where indicated on the plans, UL268/UL268A listed dual-chamber, Ionization Smoke Detectors, Fenwal Models PSD-7157 and PSD-7157D. Photoelectric Smoke Detectors containing a radioactive source of strength greater than 0.8 microcuries (29.6 kbq) shall not be acceptable. The combination detector head and twist-lock base shall be UL Listed compatible with a UL Listed fire alarm control unit. The Models PSD-7157 and PSD-7157D Photoelectric Smoke Detectors shall share interchangeable bases with the CPD-7054 and CPD-7054D Ionization Smoke Detectors and the THD-7052 and THD-7053 Heat Detectors. The Fenwal Models PSD-7157 and PSD-7157D Photoelectric Smoke Detectors shall have two Red LEDs located diametrically opposite each other so as to allow 360-degree viewing. The LEDs shall continuously indicate the operating condition of the Detector. During standby, the LEDs shall flash once every six seconds. During alarm, both LEDs shall light steady at full brilliance. If the sensitivity of the detector drifts outside acceptable limits, the LEDs shall double flash every six seconds. The detector may be reset by actuating the control panel reset switch. The vandal-resistant security locking feature shall be used in those areas as indicated on the drawings. The locking feature shall be field removable when not required. It shall be possible to measure the sensitivity of the Fenwal Models PSD-7157 and PSD-7157D Photoelectric Smoke Detectors from a distance of up to 15 feet (4.6 m) without removal from the base. Measurement shall be accomplished with a wireless infrared Fenwal Sensitivity Tester (DST-003) allowing direct measurement in percent - 2 -

per foot obscuration. Sensitivity measurement techniques requiring wiring between the Detector-Base combination and the Tester shall not be acceptable. It shall also be possible to perform a functional test of the detector without the need for generating smoke. The Fenwal Models PSD-7157 and PSD-7157D Photoelectric Smoke Detectors shall operate over an input voltage range from 10.2 to 36.8 Vdc. Voltage and RF transient suppression techniques to withstand up to 20 volt/meter shall be employed to minimize susceptibility to false alarms..
